Vladimír Beneš– EMBL

Vladimír Beneš, PhD, Head of EMBL GeneCore, born & studied in Prague, the Czech Republic. He has been at EMBL since 1994 when he came as a postdoc to Ansorge group in the Biochemical Instrumentation Unit. Vladimir worked on development of methodology supporting genome-wide high-throughput sequencing, mainly in the sample processing part. In 2001 he was appointed to build EMBL Genomics Core Facility, a technology orientated service laboratory founded to assist researchers with functional genomics projects. This facility is currently utilizing mainly massively parallel sequencing in its both short as well as long form and supporting technologies, such as qPCR, for example.

Jethro Johnson – Kennedy Institute of Rheumatology

I am an Innovation Track Principal Investigator at the Kennedy Institute of Rheumatology and Deputy Director of the Oxford Centre for Microbiome Studies.

My research uses multi-omic and computational approaches to identify the molecular basis of host-gut microbiome interactions and understand their impact on health and disease.

In 2012 I completed a PhD in nutritional ecology at the University of Auckland, New Zealand, focussing on the effects of temperature on microbially-mediated digestion in ectothermic herbivores. I subsequently transitioned from wet to dry-lab research via an MRC career development fellowship in computational genomics, working with Professor Chris Ponting and Dr Andreas Heger at the Oxford MRC Functional Genomics Unit. As a postdoctoral research associate, I moved to the lab of Professor George Weinstock at the Jackson Laboratory for Genomic Medicine, Connecticut, USA, where I applied next-generation sequencing and computational genomic approaches to characterize the human microbiome. In particular, I focussed on the role of the microbiome in metabolic disease, working on the type 2 diabetes arm of the NIH Integrative Human Microbiome Project. I joined the Kennedy Institute in 2020 to establish my own research group and help run the OCMS.

John Lees – EMBL-EBI

My previous work has attempted to understand the pathogenesis and transmission of infectious diseases. I primarily works on statistical genetics, genomic epidemiology and genome evolution of pathogenic bacteria. I have also worked on infectious disease modelling, GPU algorithms, and visualisation. I write methods and software to scale these analyses and make them more accessible to others in attempts to democratise bioinformatics. I currently lead the pathogen informatics and modelling group at EMBL-EBI.

Richard Leggett Earlham Institute

Richard Leggett is a Group Leader at the Earlham Institute in Norwich. He leads a research group focussed on developing new tools and methods for analysing environmental and clinical metagenomic samples, particularly focussed on in-field sequencing and real-time analysis. Much of the group’s work focusses on nanopore technology, but they also work with PacBio and Illumina data.
